RESUMO
To control human-to-human mpox transmission during the 2022 outbreak, European Union (EU)/European Economic Area (EEA) countries conducted case investigation and contact tracing (CT). We aimed to provide an overview of CT activities, describe CT data collection practices, and identify related facilitators, barriers, and potential opportunities for improvement. Between April 03, 2023 and May 12, 2023, a survey was distributed to CT stakeholders in 30 EU/EEA countries, asking about mpox CT activities and data collection and requesting to rank enablers, barriers, and improvements for CT on a five-point Likert scale. The 139 respondents from 27 countries indicated having performed case investigations (96%, n = 133), backward CT (88%, n = 122), forward CT (87%, n = 121), and follow-up on contacts' outcomes (77%, n = 107). Sixty percent (n = 80/134) used standardized data collection forms and 73% (n = 91/124) used databases. The highest-rated enablers were clear guidelines (mean = 3.9), quick access to laboratory results (3.6), and sufficient expertise (3.6). Highly rated barriers were inability to contact contacts (3.0) or cases (2.5) and lack of staff (2.4). The most needed improvements were availability of staff (3.5), expertise on affected populations (3.4) and data reporting tools and systems (3.3). To improve CT of mpox and diseases with similar transmission patterns, EU/EEA countries should increase workforce capacity in public and sexual health, offer training on CT operations and communication with affected communities, and use common CT data collection tools and systems.

BACKGROUND: Population-based cancer registries (PBCRs) are the primary source of information for cancer surveillance and monitoring. Currently, there are 30 active PBCRs in Brazil. The objective of this study was to analyze the data quality of five gastrointestinal cancers (esophagus, stomach, colorectal, liver, and pancreas) according to the criteria of comparability, validity, completeness, and timeliness in Brazilian cancer registries. METHODS: This study included data from Brazilian PBCRs with more than ten years of historical data starting in the year 2000, regardless of the type of defined geographical coverage (state, metropolitan region, or capital), totaling 16 registries. Brazilian PBCRs were evaluated based on four international data quality criteria: comparability, validity (accuracy), completeness, and timeliness. All cancer cases were analyzed, except for nonmelanoma skin cancer cases (C44) and five gastrointestinal tumors (esophageal cancer, stomach cancer, colorectal cancer, liver cancer, and pancreatic cancer) per cancer registry and sex, according to the available period. RESULTS: The 16 Brazilian PBCRs represent 17% of the population (36 million inhabitants in 2021) according to data from 2000 to 2018. There was a variation in the incidence in the historical series ranging from 12 to 19 years. The proportion of morphologically verified (MV%) cases varied from 74.3% (Manaus) to 94.8% (Aracaju), and the proportion of incidentally reported death certificate only (DCO%) cases varied from 3.0% (São Paulo) to 23.9% (Espírito Santo). High-lethality malignant neoplasms, such as liver and pancreas, had DCO percentages greater than 30% in most cancer registries. The sixteen registries have more than a 48-month delay in data release compared to the 2022 calendar year. CONCLUSION: The studied Brazilian cancer registries met international comparability criteria; however, half of the registries showed indices below the expected levels for validity and completeness criteria for high-lethality tumors such as liver and pancreas tumors, in addition to a long delay in data availability and disclosure. Significant efforts are necessary to ensure the operational and stability of the PBCR in Brazil, which continues to be a tool for monitoring cancer incidence and assessing national cancer control policies.

BACKGROUND: . Splash pads for recreational purposes are widespread. Using these pads can pose a health risk if they lack installation regulation and water quality supervision. Our aim was to describe a waterborne disease outbreak caused by Clostridium perfringens and Cryptosporidium spp. in a Barcelona district and the measures taken for its control. METHODS: . On August 2018, 71 cases of acute gastroenteritis were detected, affecting people who used a splash pad or were in contact with a user. Microbiological and environmental investigations were carried out. A descriptive analysis of the sample and Poisson regression models adjusted for age and sex were performed, obtaining frequencies, median values, and adjusted prevalence ratios with their 95% confidence intervals. RESULTS: The median age of the cases was 6.7 years, 27 (38%) required medical care, and three (4.2%) were hospitalized. The greater the number of times a person entered the area, the greater the number of symptoms and their severity. Nineteen (76%) of the 25 stool samples collected from cases showed the presence of one or both pathogens. Environmental investigations showed deficiencies in the facilities and identified the presence of both species in the splash pad. Health education and hygiene measures were carried out, and 14 days after the closure of the facilities, no more cases related to the pad were recorded. CONCLUSIONS: . Specific regulations are needed on the use of splash pads for recreational purposes. Until these regulations are in place, these types of facility should comply with the regulations that apply to swimming pools and spas, including those related to the design of the tanks, water recirculation systems, and adequate disinfection systems.

Four infants potentially exposed to syphilis infection in utero, meeting World Health Organization surveillance criteria of congenital syphilis (CS), were diagnosed in Croatia between September 2020 and January 2024. We conducted a retrospective analysis of epidemiological, clinical and laboratory data of these cases to assess compliance with surveillance case definitions. As only one confirmed CS case has been reported in Croatia in over 2 decades, these reports signal an increased risk of syphilis vertical transmission and warrant strengthening antenatal screening.

In January 2024, a child was diagnosed with measles in a paediatric hospital in Lisbon. Of 123 contacts, 39 (32%) were not fully immunised, presenting a risk for a potential outbreak. The public health unit initiated control measures and identified challenges during the response, such as the lack of interoperability between information systems and accessing vaccination records. The lessons learned prompted changes to national contact tracing procedures for measles, further strengthening Portugal's preparedness.

The register of malignant mesotheliomas can still play an informative role in the context of both remediation activities and the health surveillance of former asbestos-exposed persons, and become an epidemiological surveillance system on the harmful effects of exposure to asbestos. It must, however, maintain and improve the level of quality achieved, resolve the problems that have emerged in the interaction between the local level (where cases and their exposure histories are identified, registered, assessed, and medical insurance procedures activated) and the central insurance body that also manages the national register, and become an active participant in research, including clinical research. All this is important to meet the social and welfare justice needs of individual cases.

BACKGROUND: The epidemiological surveillance of contact dermatitis is one of the objectives of the Spanish Registry of Research in Contact Dermatitis and Cutaneous Allergy. Knowing whether the prevalence of positive tests to the different allergens changes over time is important for this monitoring process. OBJECTIVES: To describe the various temporary trends in allergen positivity in the GEIDAC standard series from 2018 through December 31, 2022. METHODS: This was a multicenter, observational trial of consecutive patients analyzed via patch tests as part of the study of possible allergic contact dermatitises collected prospectively within the Spanish Registry of Research in Contact Dermatitis and Cutaneous Allergy. The data was analyzed using 2 statistical tests: one homogeneity test (to describe the changes seen over time) and one trend test (to see whether the changes described followed a linear trend). RESULTS: A total of 11327 patients were included in the study. Overall, the allergens associated with a highest sensitization were nickel sulfate, methylisothiazolinone, cobalt chloride, methylchloroisothiazolinone/methylisothiazolinone, and fragrance mix i. A statistically significant decrease was found in the percentage of methylisothiazolinone positive tests across the study years with an orderly trend. CONCLUSIONS: Although various changes were seen in the sensitizations trends to several allergens of the standard testing, it became obvious that a high sensitization to nickel, methylchloroisothiazolinone/methylisothiazolinone and fragrances mix i remained. Only a significant downward trend was seen for methylisothiazolinone.

OBJECTIVE: To evaluate the behavior of the viruses responsible for acute respiratory infections before (2016-2019) and after (2020-2021) the start of the circulation of the SARS-CoV-2 virus in pediatric patients treated at a reference center from Barranquilla, Colombia. MATERIALS AND METHODS: A descriptive observational study was carried out, and data were obtained by reviewing the influenza-like illness and severe acute respiratory infection database in the pediatric population of the sentinel surveillance reference center in the district of Barranquilla during the years 2016-2021, applying inclusion and exclusion criteria. RESULTS: During 2016-2019, the average age of individuals was 1.3 (±1.7) years, during 2021, it was 2.3 (±3.5) years. The distribution by sex was similar, predominantly male. August and February were the months with the highest record of symptoms for 2016-2019 and 2021, respectively, the most frequent being cough, fever, shortness of breath, and diarrhea. By 2021 there was a higher use of antibiotics and antivirals reported than in 2016-2019. Most patients tested negative for viral detection. When comparing the percentage of viruses detected by age group and years of detection, positivity was lower in 2021 by every age group, and respiratory syncytial virus (RSV) was the most frequently detected. CONCLUSIONS: There was less virus positivity in viral detection tests in the pediatric population in 2021. RSV persists as the main etiology affecting this population, especially infants. The use of antibiotic therapy in viral infections continues to be a problematic practice in their management. Sentinel surveillance can be strengthened throughout the country.

The Omicron variant of concern (VOC) has surged in many countries and replaced the previously reported VOC. To identify different Omicron strains/sublineages on a rapid, convenient, and precise platform, we report a novel multiplex real-time reverse transcriptase polymerase chain reaction (RT-PCR) method in one tube based on the Omicron lineage sequence variants' information. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) subvariants were used in a PCR-based assay for rapid identification of Omicron sublineage genotyping in 1000 clinical samples. Several characteristic mutations were analyzed using specific primers and probes for the spike gene, del69-70, and F486V. To distinguish Omicron sublineages (BA.2, BA.4, and BA.5), the NSP1:141-143del in the ORF1a region and D3N mutation in membrane protein occurring outside the spike protein region were analyzed. Results from the real-time PCR assay for one-tube accuracy were compared to those of whole genome sequencing. The developed PCR assay was used to analyze 400 SARS-CoV-2 positive samples. Ten samples determined as BA.4 were positive for NSP1:141-143del, del69-70, and F486V mutations; 160 BA.5 samples were positive for D3N, del69-70, and F486V mutations, and 230 BA.2 samples were without del69-70. Screening these samples allowed the identification of epidemic trends at different time intervals. Our novel one-tube multiplex PCR assay was effective in identifying Omicron sublineages.

OBJECTIVES: To analyse the flow of cases of visceral leishmaniasis (VL) in the state of Ceará, Brazil, between 2007 and 2021. METHODS: An ecological study was conducted using a spatial approach of newly confirmed cases of VL recorded in the Notifiable Diseases Information System. We identified individuals whose municipality of diagnosis differed from that of their residence. Flow maps, constructed using Tabwin 32 and ArcMap 9.2, allowed for the identification of the volume of traffic between the municipality of residence and that of initial care. RESULTS: There were 6775 confirmed VL cases. As a flow indicator, 178 counties had at least one resident diagnosed in another municipality in Ceará, with 2491 VL cases and an average trip of 79 km. The largest hub for receiving cases for diagnosis was the capital Fortaleza (1478 patients from 129 other municipalities), followed by Sobral, located in the northwestern region of Ceará (599 from 55 municipalities), and Barbalha, in the southern region (171 from 29 municipalities). In this southern region, 25 municipalities moved 55 people for treatment to Juazeiro do Norte and 11 municipalities moved 39 patients to Crato. A total of 255 patients with VL from 11 municipalities in other Brazilian states, mainly from the Northeast and North, were observed and notified in health services in Ceará. CONCLUSIONS: The major centres of VL diagnosis outside residence were in the cities of Fortaleza, Sobral, Barbalha, Juazeiro do Norte and Crato. There was also an outflow of cases from other municipalities located in the northeastern and northern regions of Brazil. The flows were more intense during the first triennium of the analysis and milder from 2019 to 2021. Understanding the diagnostic flow of VL helps in decision making and the development of public policies to improve the lives of the population.

BACKGROUND: To improve the patient care, public health surveillance, and infection control, it is crucial to identify the presence and frequency of the common respiratory infections in individuals with COVID-19 symptoms but tested negative for SARS-CoV-2. This study aimed to shed light on this during the COVID-19 pandemic in Iran. METHODS: In this cross-sectional study, a total of 1,002 patients with acute respiratory infection who had negative SARS-CoV-2 test results and referred to Valfajr Health Center, the National Collaborating Laboratory of Influenza and COVID-19 National Reference Laboratory at Pasteur Institute of Iran were recruited between January 2020 and January 2022. Nasopharyngeal and oropharyngeal swab samples were collected to detect 17 common respiratory viruses via TaqMan one-step real-time multiplex PCR. Demographic and clinical data of the participants were obtained from their electronic medical records. RESULTS: In total, 218 samples (21.8%) were tested positive for at least one respiratory virus infection. Most of the common investigated respiratory viruses belonged to the years 2020 and 2022. The number of investigated patients in 2021 was few, which highlights the impact of health measures following the COVID-19 pandemic in Iran. Influenza A was the most common virus (5.8%), while adenovirus had the lowest prevalence (0.1%). Although the rate of respiratory virus infection was higher in men (24%) compared to women (19.3%), this difference was not statistically significant (P = 0.069). The prevalence of respiratory viruses had an inverse association with increasing age, with the highest rate (55.6%) observed in the age group below 2 years and the lowest rate (12.7%) in those above 65 years. CONCLUSION: Our findings underscore the significance of adopting a comprehensive approach to respiratory infections detection and management. These results can be employed for the development of syndromic surveillance systems and implementation of the effective infection control measures. Furthermore, the results contribute to better understanding of the dynamics of respiratory viruses, both during pandemic periods and in non-pandemic contexts.

BACKGROUND: The potential to harness the plurality of available data in real time along with advanced data analytics for the accurate prediction of influenza-like illness (ILI) outbreaks has gained significant scientific interest. Different methodologies based on the use of machine learning techniques and traditional and alternative data sources, such as ILI surveillance reports, weather reports, search engine queries, and social media, have been explored with the ultimate goal of being used in the development of electronic surveillance systems that could complement existing monitoring resources. OBJECTIVE: The scope of this study was to investigate for the first time the combined use of ILI surveillance data, weather data, and Twitter data along with deep learning techniques toward the development of prediction models able to nowcast and forecast weekly ILI cases. By assessing the predictive power of both traditional and alternative data sources on the use case of ILI, this study aimed to provide a novel approach for corroborating evidence and enhancing accuracy and reliability in the surveillance of infectious diseases. METHODS: The model's input space consisted of information related to weekly ILI surveillance, web-based social (eg, Twitter) behavior, and weather conditions. For the design and development of the model, relevant data corresponding to the period of 2010 to 2019 and focusing on the Greek population and weather were collected. Long short-term memory (LSTM) neural networks were leveraged to efficiently handle the sequential and nonlinear nature of the multitude of collected data. The 3 data categories were first used separately for training 3 LSTM-based primary models. Subsequently, different transfer learning (TL) approaches were explored with the aim of creating various feature spaces combining the features extracted from the corresponding primary models' LSTM layers for the latter to feed a dense layer. RESULTS: The primary model that learned from weather data yielded better forecast accuracy (root mean square error [RMSE]=0.144; Pearson correlation coefficient [PCC]=0.801) than the model trained with ILI historical data (RMSE=0.159; PCC=0.794). The best performance was achieved by the TL-based model leveraging the combination of the 3 data categories (RMSE=0.128; PCC=0.822). CONCLUSIONS: The superiority of the TL-based model, which considers Twitter data, weather data, and ILI surveillance data, reflects the potential of alternative public sources to enhance accurate and reliable prediction of ILI spread. Despite its focus on the use case of Greece, the proposed approach can be generalized to other locations, populations, and social media platforms to support the surveillance of infectious diseases with the ultimate goal of reinforcing preparedness for future epidemics.

BackgroundMultidrug-resistant (MDR) bacteria are among chief causes of healthcare-associated infections (HAIs). In Spain, studies addressing multidrug resistance based on epidemiological surveillance systems are lacking.AimIn this observational study, cases of HAIs by MDR bacteria notified to the epidemiological surveillance system of Andalusia, Spain, between 2014-2021, were investigated. Notified cases and their spatiotemporal distribution were described, with a focus on social determinants of health (SDoH).MethodsNew cases during the study period of HAIs caused by extended-spectrum ß-lactamase (ESBL)-/carbapenemase-producing Enterobacterales, MDR Acinectobacter baumannii, MDR Pseudomonas aeruginosa or meticillin resistant Staphylococcus aureus were considered. Among others, notification variables included sex and age, while socio-economic variables comprised several SDoH. Cases' spatial distribution across municipalities was assessed. The smooth standardised incidence ratio (sSIR) was obtained using a Bayesian spatial model. Association between municipalities' sSIR level and SDoH was evaluated by bivariate analysis.ResultsIn total, 6,389 cases with a median age of 68 years were notified; 61.4% were men (n = 3,921). The most frequent MDR bacteria were ESBL-producing Enterobacterales (2,812/6,389; 44.0%); the main agent was Klebsiella spp. (2,956/6,389; 46.3%). Between 2014 and 2021 case numbers appeared to increase. Overall, up to 15-fold differences in sSIR between municipalities were observed. In bivariate analysis, there appeared to be an association between municipalities' sSIR level and deprivation (p = 0.003).ConclusionThis study indicates that social factors should be considered when investigating HAIs by MDR bacteria. The case incidence heterogeneity between Andalusian municipalities might be explained by SDoH, but also possibly by under-notification. Automatising reporting may address the latter.

BackgroundTick-borne encephalitis (TBE) is the most common viral central nervous system (CNS) infection in Poland. Previous research suggests that its incidence was underestimated in the pre-pandemic period. The COVID-19 pandemic caused a considerable burden on surveillance systems, which could further impact reporting.AimWe aimed to assess the completeness of reporting of TBE in the years 2008 to 2020 and explore the potential impact of the COVID-19 pandemic on reporting to the epidemiological surveillance system, compared with hospitalisations for TBEV and other viral neuro-infections.MethodsWe compared the Polish epidemiology of TBE and other viral infections of the CNS from national surveillance reports with data on hospitalisations from 2008 to 2020 and data from selected European countries.ResultsBetween 2008 and 2020, 3,016 TBE cases were reported to surveillance compared with 3,620 hospitalisations. There was an increasing trend in hospitalisations, while surveillance data demonstrated the opposite, with the largest discrepancy observed in the first pandemic year (354 hospitalisations vs 159 cases reported to surveillance). Serological testing for TBE was used more in the known endemic region of north-eastern Poland and less in non-endemic areas. Other European countries reported higher TBE case numbers and an increase during the COVID-19 pandemic, whereas Poland observed an opposite trend.ConclusionThe sensitivity of TBE surveillance in Poland requires improvement. There are considerable regional differences. Regions that test for TBE intensively report most cases. Policymakers should be made aware of the value of quality epidemiological data for planning prophylactic measures in risk areas.

Introduction: It is unclear if SARS-CoV-2 has affected people living with HIV (PLWH) more. Methods: We compared SARS-CoV-2 testing, test positivity, hospitalisation, intensive care unit (ICU) admission, and mortality between PLWH and the general HIV-negative population of Catalonia, Spain from March 1 to December 15, 2020. Results: SARS-CoV-2 testing was lower among PLWH 3556/13,142 (27.06%) compared to the general HIV-negative population 1,954,902/6,446,672 (30.32%) (p < 0.001) but test positivity was higher among PLWH (21.06% vs. 15.82%, p < 0.001). We observed no significant differences between PLWH and the general population in terms of hospitalisation (13.75% vs. 14.97%, p = 0.174) and ICU admission (0.93% vs. 1.66%, p = 0.059). Among positive cases, we found a lower mortality rate among PLWH compared to the general population (1.74% vs 3.64%, p = 0.002). Conclusion: PLWH tested less frequently for SARS-CoV-2, had a higher test positivity, similar ICU admission and hospitalisation rates, and lower SARS-CoV-2-associated mortality compared to the general HIV-negative population.
Introducción: No está claro si el SARS-CoV-2 ha afectado más a las personas que viven con VIH (PVV). Métodos: Se compararon los test realizados de SARS-CoV-2, la positividad de la prueba, la hospitalización, los ingresos en la unidad de cuidados intensivos (UCI), las tasas de mortalidad entre PVV y la población general de Cataluña desde el 1 de marzo hasta el 15 de diciembre de 2020. Resultados: Los test realizados de SARS-CoV-2 fueron menos entre PVV 3.556/13.142 (27.06%) comparado con la población general de Cataluña 1.954.902/6.446.672 (30,32%) (p < 0,001), pero la positividad de la prueba de SARS-CoV-2 fue mayor entre las PVV (21,06 vs. 15,82%; p < 0,001). No se observaron diferencias estadísticamente significativas entre PVV y la población general en cuanto a hospitalizaciones (13,75 vs. 14,97%; p = 0,174) e ingresos en la UCI (0,93 vs. 1,66%; p = 0,059). Entre los casos positivos, se encontró una menor tasa de mortalidad entre las PVV en comparación con la población general (1,74 vs. 3,64%; p = 0,002). Conclusiones: Las PVV fueron testadas menos frecuentemente por SARS-CoV-2 que la población general, tuvieron una tasa de positividad más elevada, tasas similares de hospitalización e ingresos en la UCI, y menos mortalidad asociada al SARS-CoV-2.
RESUMO
Conceptual and operational aspects of studying and promoting environmental justice and the results from assessments on environmental justice carried out within the epidemiological surveillance SENTIERI focused on communities living close to main Italian contaminated sites are here summarized. The communities under SENTIERI surveillance often have environmental injustice conditions associated with the cumulative impact of environmental pressures due to contamination and a high socioeconomic deprivation and mortality risk. In Italy, a North-South divide gradient is present, with the worst conditions in the South&Island, where most communities affected by contaminated sites are socioeconomically deprived. The main mechanisms of development and maintenance of distributive injustice in contaminated sites are attributable to procedural injustice conditions, with marginalization and misrecognition of disadvantaged communities or subgroups in decisional processes regarding both the location and permanence of polluting industrial plants and the interventions on remediation and reduction of hazardous exposures and health-related impacts. Within SENTIERI, strategies have been developed to produce participative territorial communication plans and to strengthen the environmental health literacy of local institutional and social actors. SENTIERI contributes in promoting environmental justice through the empowerment of social capacities of local communities.

BACKGROUND: the relationship between past asbestos exposure and the onset of malignant mesothelioma (MM) is well established. However, defining the exposure is not always easy, as it occurs decades before the onset of the disease. OBJECTIVES: this report describes four cases of MM diagnosed in two different married couples, both exposed to asbestos fibers: husbands at work and wives for cohabiting and washing their work overalls. DESIGN: case report. METHODS: the information was collected through interviews using a semi-structured questionnaire and analyzed by occupational hygienists during the activity of epidemiological surveillance of this disease. The results of the mineral content of asbestos fibers performed on lung parenchymal from one of the female cases are available. RESULTS: these two cases show a longer latency in the lesser exposed confirming what an occupational epidemiological study has recently highlighted. CONCLUSIONS: whenever good quality information collected during interviews are available, skilled occupational hygienists are able to reconstruct past exposures in quali-quantitative terms.

This paper describes the development and the envisioned use of concept maps in the framework of the SENTIERI communication strategies as an information and scientific communication tool applied to epidemiological surveillance in contaminated sites. The concept map of SENTIERI 2019-2022 was designed and implemented to foster access to complex scientific information ensuring usability of the contents and communication with the various stakeholders. The concept map aims to promote environmental health literacy in contaminated sites. The methodology adopted to create the map includes the following phases: 1. choice of a dynamic focus question; 2. selection of the representative terms of the addressed topics; 3. elaboration of the glossary of the selected terms; 4. representation of the links among the selected terms; 5. identification of the significant propositions that make explicit the meaning of each link. Online access to the map is guaranteed by the Mindomo software. The use of the concept map promotes active learning of the topics that characterize SENTIERI 2019-2022 through knowledge paths chosen because of the specific interests and learning purposes. The concept map derives from the integration of specific approaches of the epidemiological discipline with those of the social sciences and offers the possibility of developing site-specific maps through the interactions with local actors and the integration of elements related to emerging problems as well as institutional and local interests.

BACKGROUND & AIMS: It remains unclear whether rectal colonization with multidrug-resistant organisms (MDROs) is prevalent and predisposes to infections by the same pathogens in patients with cirrhosis. METHODS: Two series of critically ill patients were evaluated. In the Barcelona cohort, 486 consecutive patients were prospectively evaluated, 129 with and 357 without cirrhosis (2015-2016). Rectal swabs were performed at admission and weekly thereafter (until intensive care unit [ICU] discharge) to detect MDRO colonization. Risk factors for colonization and infection by MDROs were evaluated. A retrospective cohort from Frankfurt (421 patients with cirrhosis; 2010-2018) was investigated to evaluate MDRO rectal colonization in another epidemiological scenario. RESULTS: In the Barcelona cohort, 159 patients were colonized by MDROs (32.7%), 102 (64.2%) at admission and 57 (35.8%) during follow-up. Patients with cirrhosis showed higher rates of rectal colonization at admission than those without cirrhosis (28.7% vs. 18.2%, p = 0.01) but similar colonization rates during ICU stay. Extended-spectrum beta-lactamase-Enterobacterales were the most frequent MDROs isolated in both groups. Colonization by MDROs independently increased the risk of infection by MDROs at admission and during follow-up. Risk of new infection by the colonizing strain was also significantly increased in patients with (hazard ratio [HR] 7.41) and without (HR 5.65) cirrhosis. Rectal colonization by MDROs was also highly prevalent in Frankfurt (n = 198; 47%; 131 at admission [66.2%] and 67 [33.8%] during follow-up), with vancomycin-resistant enterococci being the most frequent colonizing organism. Rectal colonization by MDROs was also associated with an increased risk of infection by MDROs in this cohort. Infections occurring in MDR carriers were mainly caused by the colonizing strain. CONCLUSION: Rectal colonization by MDROs is extremely frequent in critically ill patients with cirrhosis. Colonization increases the risk of infection by the colonizing resistant strain. LAY SUMMARY: Rectal colonization by multidrug-resistant organisms (MDROs) is a prevalent problem in patients with cirrhosis requiring critical care. The pattern of colonizing bacteria is heterogeneous with relevant differences between centers. Colonization by MDROs is associated with increased risk of infection by the colonizing bacteria in the short term. This finding suggests that colonization data could be used to guide empirical antibiotic therapy and de-escalation policies in patients with cirrhosis.
